So my 89 iroc 305 is giving me crap. I finally got to drive it. When I fire it up, it chokes out and bogs and is literally not driveable. Anytime I hit the gas it just immediately sputters and chokes. But, after revving it a while I got it to rev somewhat smoothly. I pu it back in drive and then drove it more and it got better as it got hotter. Once it hit 220 degress it ran acceptably. I could hit the gas from a stop and it would go. It would sputter a little, but barely. Then I shut the car off for thirty minutes and started it before it was cold and the same damn thing started again. Bogged out until I got it running for about 5 minutes, then I could drive it.

I have the wrong tps on it it's from a v6, but would this be a cause to this problem? It seems to run fine when it's been running for a little while. I'm stumped and I need immediate help

 

hey i just got a 1986 camaro with a 92 v8 5.7 liter engine in it . the car was running really crappy so i had to change firing order on the car it was running alot better.. but still wasnt right about a week later i discovred the smog silinoid was disconnected from the terminal where it goes into the top of the engine also the electric was not pluged into the conponent. i did some research and found out the correct way to hook it up .. i started and drove the car about 5 blocks car seamed to be running better then ever smooth and more power . after i turned the car off and tryed to start it up the next day .. car does not start .. as u hold the exnition and pump the gas the engine gets slowly to full running speed as if its running and when i let go of the exnition it turnes off as quick as i let go ?? i also tryed removing the smog silinoid back to how i org found it still same story any suggestions ?? thanks
